For example, Remote Desktop 8 is available for download for Windows 7, but it doesn't come installed by default. Plus, if I detected the OS, my code wouldn't function on the next version of Windows where something like above would continue to work. Is the concept above not valid for activeX controls?

- Remote Desktop ActiveX control interfaces.; 4 minutes to read; m; D; d; m; m; In this article. The Remote Desktop ActiveX control supports the following scriptable and nonscriptable interfaces, which are grouped according to the inheritance hierarchy.
- I also have some remote servers to look after, after some hard time I manage to make it work, HTH. Note that Network Level Authentication (NLA) is configured for Remote Desktop session to these servers, that is why I need to set the EnableCredSspSupport property. If leave this property unset, the RDP control does not show anything, and there.
Symptoms
Microsoft Edge is the new default web browser for Windows 10. However, if you're running Remote Desktop Web Access (RDWEB) or web apps that require ActiveX controls, the Edge browser may not work, and we recommend that you continue to use Internet Explorer 11.
As seen in the following side-by-side images, the Connect to a remote PC tab is missing from the Edge UI (the image on the left), but in Internet Explorer (the image on the right) this tab is still displayed.
When Internet Explorer is configured to work in this scenario, the MsRdpClientShell - MsRdpWebAccess.dll add-on is loaded as an ActiveX control.
Cause
This issue occurs because, by design, ActiveX controls aren't supported in Microsoft Edge.
Resolution
Microsoft Edge is the default browser in Windows 10, with Internet Explorer provided to handle legacy sites.
If you have specific websites and apps that have compatibility issues with Microsoft Edge, you can use the Enterprise Mode site list. This lets you continue to use Microsoft Edge as your default browser while also making sure that sites and apps that rely on Internet Explorer continue to work.
To download the Enterprise Mode Site List Manager tool from the Internet Explorer Download Center, go to Enterprise Mode Site List Manager.
To add sites to your Enterprise Mode site list, see Use Enterprise Mode to improve compatibility.

You can access computers in a Local Area Network (LAN) or in a Wide Area Network (WAN) to complete various tasks. Desktop Central supports remote desktop sharing across platforms i.e for Windows, Mac and Linux Operating Systems.
Ensure that the following prerequisites are met before you access computers remotely:
Configuring Browser Settings
You are required to configure certain controls in your browser before connecting remotely to a computer.
Ensure that you configure controls only in the browser from where a remote connection is being established.
HTML 5 Viewer is supported on the following versions of the browser: Edge (all versions), Internet Explorer 10 and later versions, Firefox 38 and later versions, Google Chrome 31 and later versions and Safari 8 and later versions.

Ports that need to be open
The following TCP ports should be open on the Desktop Central server to establish connection with a remote computer:
- 8443 : Secure port to establish remote connection.
- 8444 : Used to establish remote connection
- 8031 : Secure port for File Transfer
- 8032 : Used for File Transfer
Enabling the UDP port 8443 will let your viewer directly control your remote agent. However, an initial handshake will happen via Desktop Central server. Know more on different communication modes here.
Ensure that the above mentioned ports are opened on the Desktop Central server and are reachable from the Desktop Central agent as well as the viewer machine.
You can now configure the settings required for establishing remote connection.
